摘要
为了测定超出费氏仪读数板孔隙度范围的粉末的平均粒度 ,叙述了两种扩大仪器测量范围的方法 :( 1 )采用试样的非标准测定量 ;( 2 )绘制孔隙度扩大部分的读数曲线。并且用这两种方法测定了几种粉末的平均粒度 。
In order to determine the average particle size of powders of which the porosity range exceeds beyond the calculator chart of the Fisher sub sieve sizer.In this paper two methods to extend the measuring range of the instrument are described.One of them uses a nonstandard quantity of the samples.And the other is to draw the calculate chart to extended porosity scale.Average particle sizes of some powders are determined by above mentioned method.And satisfying results are obtained.
